BOSTON- MassDOT’s Callahan Tunnel Project begins with a full tunnel closure for rehabilitation on December 27, 2013 through March 12, 2014. The Callahan Tunnel Project web page now includes detour maps. The detour routes were carefully developed by the project team with input from stakeholders.

Vehicles heading to points south via I-93 Southbound may want to avoid traffic detoured onto Albany Street. MassDOT has opened up access to an express route to I-93 to all vehicles, regardless of occupancy.

MassDOT has made improvements to signal timing along detour routes as-needed to facilitate the flow of traffic during construction. Key intersections will be monitored during the tunnel closure by traffic engineers and police.

The $34.9 million project includes rehabilitation of the 52-year old tunnel’s deck, curb line, gutters and replacement of the tunnel’s wall panels. The original deteriorated wall panels were removed in December 2012 as a safety measure due to significant corrosion to the panel wall anchor system.

The proposed work schedule includes the full tunnel closure in early 2014 with detours in place, followed by an additional 4-5 months of work requiring overnight closures between 11p.m. and 5a.m. The complete closure of the tunnel will reduce the overall duration of the project, provide enhanced public safety by minimizing changes to traffic flow, and better coordinate with other local projects including Tobin Bridge work, which is scheduled to resume in spring 2014.
